A town can't survive on tourism alone, and we could see from the ramparts at Langres a big factory belonging to Plastic Omnium. We passed it on the way to the reservoir at Liez on our way out to our next stopping-place at Neuf-Brisach.
The reservoir itself was rather bleak on this cold and misty October morning. You can see how the summer drought has left the water level several metres lower than usual. A few hardy fishermen were standing on the dam wall, and there was someone walking a dog but no-one else was about.
A little farther on we discovered the garden snails at Cohons. There are three, and they are follies, as far as I could tell. You can walk up the spiral slope to the top, as a result of which you are a bit higher up than you were before.
